OpenDBX supports the ANSI data types which have a defined format and
semantics. Database vendors invented much more data types for special
cases which doesn't fit into the ANSI scheme. These special data types
are summarized as TYPE_UNKNOWN in OpenDBX which only means that they
doesn't fit into the existing ANSI types and their data is returned in
its native format without any conversion. So TYPE_UNKNOWN is only
another data type for all remaining database specific types.
